CCTV Analysis – Presentation for Prosecution

The UK is the world’s CCTV capital

Whatever we’re doing, wherever we’re going, chances are we’re on CCTV (Closed Circuit Television). There are an estimated 6 million CCTV’s in the UK – most of what they monitor is of course inconsequential, but where crime is being investigated CCTV provides invaluable Prosecution Digital Forensic evidence.

Sytech have developed industry-leading processes to enhance the value of this evidence – much CCTV video footage requires image clarification and authentication in order to make it suitable as Prosecution evidence and for formal presentation.

Sytech provides this complete Digital Forensic service, including the following:

Enhancement – CCTV and mobile phone recordings are most frequently of low quality. We can apply many processes to the footage to clarify the images and audio using filters that are fully documented in the finished technical report

Stabilisation – we can stabilise ‘shaky’ footage taken on mobile devices so that the person or object of interest remains static on the screen

De-multiplexing – separating multi-camera video feeds

Highlighting- either highlighting the area of the footage of interest, or blurring/pixellating area to be redacted, protecting sensitive information, identities, number plates etc

Annotating – adding titles, arrows, text to best illustrate the portion of interest, and subtitling for clarification of pertinent conversations etc

Measurement – measuring and giving context to real world distances, heights, and lengths from images or video frames, providing evidence such as a suspect’s height

Perspective – correcting and modifying the camera viewpoint in different frames with perspective alignment

Comparisons – providing comparisons between faces, persons or objects in CCTV footage, and images taken in custody suites or by our own photographer – this can include people, clothing, weapons, cars etc
